nism associated with it to prevent tampering with the resetting mechanism to fraudulently advance the count both while the counter-is locked and while it is unlocked. A further object of my invention is to provide improved locking and resettingmechanism for pick counters having improved means associated therewith for preventing advance of the count by a blow on the resetting mechanism, either following resetting and before locking or following locking of the mechanism. A still further object includes the provision of improved and simplified locking means preventing removal of the key following initiation of a resetting movement until the 20 counter wheels have been completely reset to their initial zero position, and also preventing such removaLof the key until the resetting mechanism has' been operated to disconnect the operative connection between the driving elements 25 of the resetting mechanism and the counter wheels. A still further object is to provide improved and simplified reset locking mechanism fora multiple pick counter having a common locking means and eliminating the need for a 30 transverse locking member extending across the axes of the resetting shafts of the several counters, required in' previous constructions. These and other objects and advantages of my improved construction will, however, hereinafter more fully appear.

In the construction illustrated in Figures 1-14a, I have shown my invention applied to a double pick counter mechanism of a. well known type including a casing comprising a body i and a removable cover 2 and having two like counters generally indicated at 3 and ktherein. These counters are mounted on parallel shafts B and 1 lournaled in the ends of the casing and are adapted to be driven selectively from a counter drive shaft 8 by a usual clutch mechanism,- not shown',.depending upon the position of connection of a usual manually adjustable control memher 9; one counter, herein the counter 3, being connected for use on the day shift and the other for use on the night shift. Each of said shafts has a resetting member ID located externally of the casing by which either counter maybe reset to zero, as will be hereinafter explained. The

counters 3 and. are adapted to be locked during I counting operation by improved locking mechanism, hereinafter more fully described, including a lock II and key II, as herein shown of the usual "Yale" orpin tumbler type, "controlling the'operation of the resetting members Ill.

' Referring to the counters 3 and 4, it will be noted that each of these includes a plurality of coaxial counter wheels operatively connected by the usual tens-transfer mechanism and that the two counters are identical in construction. Using the counter 3 for purposes of description, it will be noted that the same comprises three counter elements i3, i4 and i5, each including a number wheel operatively connected through usual tenstransfer mechanism of the locking type so as to register the rotation of the driving shaft 8 in terms of multiples of picks woven, with each unit on the wheel l5 representing a predetermined number of picks, as, for example, one thousand picks, each unit on the wheel l4 representing ten thousand picks, and each unit on the wheel l3 representing one hundred thousand picks.

Considering more particularly the construction of one of the counter elements l3, l4 and I5, it will be understood that each of these is identical in construction so that reference to only one is necessary. Considering counter element I3 of counter 3 it will be noted that this element, as shown in Figures 6, 7 and 8, includes a sleeve IS on which the number wheel I! is fixed and which also has fixed thereto a locking disc l8 and a mutilated transfer gear l9 on the opposite side of the locking disc Hi from the number wheel. Also, as is usual in such units, a reset pawl 20 in the disc I8 is normally pressed by a spring 2| through an aperture 22 in the sleeve l6 ready to engage with a longitudinal groove 23 in its supporting and resetting shaft 6, as will be readily understood from an inspection of Figure 6 in which the groove is slightly displaced from the pawl 20. Further, it will be noted that a driving gear 24 is rotatably mounted on the opposite end of the sleeve I6 from the mutilated transfer gear l9 and through a pair of spring pressed pawls 25 is adapted to cooperate in a usual way with a cup-shaped ratchet member 26 which is disposed within a recess in the face of the number wheel ll adjacent the gear 24. Thus, it will be evident that with the several counter units l3, l4 and I5 of counter 3 operatively connected by usual trans-1 of this application, a pick counter of this general type is shown and described in detail in which fraudulent advance of the count is prevented, both when the counter is locked and when it is unlocked, and referencels made to this prior application. The construction shown herein prevents fraudulent advance of the count by a dishonest operator even when such an operator possesses a key to the counter mechanism, and provides in a simpler and less expensive locking and resetting mechanism, the advantageous features of said earlier filed application. For instance, in the present construction the longitudinally reciprocable bar extending transversely of the resetting shafts, required in the prior construction, is entirely eliminated.

In this preferred form of my invention, the lock l l is common to both counters 3 and 4 and is supported on a bracket 28 (Figure 13) fixed to the inner Wall of the casing between the resetting shafts 8 and 1 adjacent the ends thereof carrying the resetting members I0, and includes a stationary barrel 23 formed integral with the bracket 28 and a lock plug 30 rotatable therein having a key slot 32. As is usual in this type of lock, the lock plug 30 can not be rotated in the barrel until the key i2 has been inserted in key slot 32; and, after the lock plug has been turned by the key even slightly, the key can not be withdrawn until the lock plug has been returned to its normal locking position. Herein a locking plate 34 is secured to the bottom end of the lock plug 30 for movement therewith when the latter is turned by the key i 2 and is held against rotation relative thereto by means of a pin 35 (Figure 13).

Rotatable locking members 31 (Figure 10) are fixed on the resetting shafts 6 and l in position to cooperate with the key controlled locking plate 34. For this purpose, supporting sleeves 38 (Figures 11 and 12) are fixed to said shafts between the counter elements I3 and the end wall of the casing by pins 3811 which extend through flanges 39 of said sleeves and the respective shafts 5 and I. Sleeves 38 have flattened peripheral portions 40 which cooperate with corresponding flattened portions 4| in the apertures 42 of said rotatable locking members to position the latter against rotation on said sleeves, the rotatable locking members being suitably supported against longitudinal movement on the sleeves by means of tubular spacers 43 and 44 which extend between the enlargement 39 at one end of said sleeve and a ratchet wheel 45 adjacent the casing wall. It will be noted that the ratchet wheels 45 are likewise fixed to the sleeves 38, having apertures 46 provided with flattened portions 41, as in the case of the locking members 31. The rotatable locking members 31 are also provided with rectangular notches 48 in their external peripheries which, in the zero position of the resetting shafts following resetting of the counter elements to zero and prior to locking, are disposed in the horizontal plane including the axes of resetting shafts 8 and "i and confront each other.

Considering more in detail the cooperating locking plate 34, briefly referred to above, it will be noted that this plate moves in the horizontal plane including resetting shafts 6 and "I and has diametrically opposite extensions 49a and 491), the diagonally disposed edge portions 50a and 50b of which are oppositely refiexed upwardly and downwardly, respectively, out of the plane of the plate 34. It will also be noted that when the locking plate 34 is moved clockwise by the key i2 from the unlocked position of the mechanism shown in Figure 3, into locking relation with the v locking plate 34 is moved to the mechanism locked position shown in Figure 4, due to the vertical deflection of the trailing edge portions 50!; and 5017, the plate 34 has a camming action on the rotatable locking members 31 rotating both of the latter in a clockwise direction as viewed from the left in Figure 2, i. e., in a direction opposite to the direction of rotation of the shaft during resetting as indicated by the arrows in Figure 2. The rotation of the resetting shafts 6 and 1 due to the camming action of plate 34, as herein shown, is sufficient to rotate the resetting shafts 8 and if reversely through an angle of approximately 12 degrees into a position in which the resetting grooves 23 are withdrawn from the resetting pawls 28 as illustrated in Figures 4 and 6.

Mechanism is also provided, including the ratchet wheel 45 previously mentioned, for preventing reverse rotation'of the resetting shafts 6 and 7.7 in certain positions of the latter. As shown most clearly in Figure 4, the ratchet wheels 45 are provided with a series of teeth 53, herein four in number, which cooperate with spring pressed pawls 54 carried by the end wall of the casing I, the pawls riding over the teeth and the untoothed portion on the periphery of the ratchet wheels 45 and dropping in back of each tooth as said wheels are rotated past the stationary pawls during resetting.v Thus, it will be evident from an inspection of Figure 4 that if a resetting shaft is rotated in a resetting direction enough to advance a number wheel I! even slightly, the pawl 33 associated with that counter will drop in back of a tooth in such manner as to prevent a return movement of the shaft and compel the operator to continue the resetting movement before he can lock the counter mechanism. Here, it will be noted that the position of the pawls following a complete resetting movement of the number wheels to zero is such as to permit the limited reverse rotation of the ratchet wheels due to the camming action above described.

In the use of this form of my invention, it will be understood that the counter mechanism is locked during operation of the loom and that the supervisor at the end of the day or the week, after recording the readings of the day or night counter, or, if desired, of both counters, is able to unlock the counter mechanism by inserting the key l2 in lock II and turning the key to rotate the locking plate 34 from the mechanism locked position of Figure 2 into the unlocked position of Figure 3, releasing both rotatable locking members 31. He is then able to rotate either or both shafts 6 and l, as may be desired, in the resetting direction indicated by arrows in Figure 2 and reset one or both of the counters to zero position by resetting members In. Following a completed resetting movement of either or both counters, and only then, can the key be turned again to the mechanism locked position of Figure 2- in which it can be withdrawn. Thus the w'eaver is not only prevented from tampering with the resetting mechanism, but carelessness on the part of the supervisor is also prevented, since he can not lock the mechanism and withdraw his key until the counter or counters he has reset have been properly returned to zero position.

In Figures 15-24, I have illustrated another construction which may be used advantageously when it is not desired to reset the counters 3 and 4 separately. In this modified construction only one resetting member ID is provided, the resetting member on shaft 6 being omitted and this shaft being shortened to terminate in the casing wall.

Both counters 3 and 4 are reset by the single operating member lll provided on shaft 1. To this end each resetting shaft has a spur gear 56 carried on its sleeve 38 in place of the ratchet wheels 45, each of said gears, as shown most with the flattened portions 40 of, the sleeves.

clearly in Figure 17, having an aperture provided with a flattened portion 58 which corresponds An intermediate idle gear 59 on drive shaft 60 operatively connects the gears 56 and has a spring pressed pawl 6| which is carried by the casing cooperating with the teeth thereof to prevent reverse rotation of the gear train. It will be evident that, when the wing nut I is turned to rotate shaft 1 in the resetting direction, shaft 6 will be rotated in the same direction to reset both counters in unison.

Due to the operative; connection of the two counter shafts through the train including gears 56 and 59, the locking means, in this construction,

cooperates directly with the resetting mechanism of one counter only, herein. the counter 4. Accordingly,'a lock 62 having a key 63 is provided in the corner of the casing adjacent the resetting shaft 1. This lock is of the usual Yale or pin tumbler type, previously described, andhas a locking plate 64 (Figure 19) which is fixed to the lock plug 30 above the barrel 29 in the space between the top of said barrel and the cover 2 (Figure 21). The plate 64 is provided with a projection 65 which lies in the slot 32 in the lock plug so that upon insertion of the key 63 in said slot and rotation of the lock plug by the key, the looking plate 64 will be swung from the locking position shown in Figure 16, in the direction of the arrow indicated in that figure, into unlocked position. A cooperating rotatable locking member 66 is provided onthe sleeve 38 of shaft 1, secured against rotation relative thereto by a flattened portion 61 cooperating with the flattened portion 40 of said sleeve. The locking member also has a flattened portion 68 on its external periphery, which, in the normal locked position of the mechanism, is horizontally disposed at the top, as shown in Figure 17, beneath the locking plate 64. It will be, evident that in this position of the locking plate 64 in which it overlies the flattened portion 68, the counter resetting shaft 1 of counter 4, and hence also the resetting shaft 6 of counter 3, are locked against rotation.

As in the preferred form above described, if the counter is locked with the resetting mechanism in the zero position of the number wheels immediately following resetting, i. e., with the reset pawls 20 in the resetting grooves 23, it is possible to advance the count by tapping the resetting wing nut to jump ahead one or more of the counter wheels I! while the resetting mechanism is locked. This form of cheating is prevented in this modified construction, as in the above construction, by means for reversely rotating the resetting shafts during locking of the mechanism. It will be noted (Figure 21) that in the position of the locking disc 66 immediately following a resetting operation and prior to locking, the flattened portion 68 of the rotatable locking disc is rotated beyond its normal locking position shown in Figure 17 and is angularly related to the horizontal locking plate 64. Accordingly when the locking plate 64 is swung from the unlocked position of Figure 21 to the locking position of Figure 16, the rotatable locking member 66 will be rotated reversely into a position in which the resetting grooves 23 of shafts 6 and l are withdrawn from engagement with the resetting pawls 20, as shown in Figure 6. In this position of the parts a blow against the resetting wing nut [0 can not be transmitted through the grooves 23 to the resetting pawls, and fraudulent advance of the counter wheels by this method is prevented. The lower corner of locking plate 64 is preferably bevelled, as indicated at 69, where it engages the rotatable locking member 66, as illustrated most clearly in Figures 19 and 20, This movement of the locking plate is limited by the margins 10 in the locking plate 64 which engage a pin H in the ball clutch type which, while not preferred, may be used in place of the pawls and ratchets illustrated in the two embodiments of my invention. As shown herein, the ball clutch mechanism is illustrated in connection with the locking structure of Figures 1 to 14a. It will be noted that the sleeve 00 of that locking mechanism is replaced by a special sleeve i2 which is secured to the resetting shaft, as the shaft 0, by a pin H3. The sleeve is formed with a reduced end portion adjacent the counter element [l3 forming a shoulder 710 against which the locking member 3? abuts, and is also provided with a hat portion ill which cooperates with the corresponding flat portion 00 of the locking member, as previously described. A spacing member V5 is held in place by the pin l3 and serves to hold the locking member in place against the shoulder iii. The sleeve W has tapered, circumferential ball receiving grooves l6, herein three in number, at its opposite end, adjacent the casing end wall, in each of which a spring pressed ball llll is disposed in position to frictionally engage a cup-shaped ball retaining memher it carried by the casing wall, which permits free rotation of the sleeve relative thereto in one direction while gripping the same by the clamping action of the balls upon opposite rotation of the.

sleeve in a manner well known in friction clutches of this type. The cup-shaped ball retaining mem her it has its end wall partly removed, forming an aperture l0 therein having opposed flat surface edges which receive somewhat loosely therebetween the corresponding opposed, flat surfaces of a hub iii formed on the casing wall and extending into said aperture it. It will be evident from Figure 23 that, as a consequence of the loose iit of the corresponding flat surfaces on 8i and it, the retaining cup 178 will permit the limited rotation of the resetting shaft 6 required by the locking mechanism, as previously described, to pro-= vide the important blow-proof feature of the present construction, while limiting this reverse rotation to that required for this purpose.

It will be understood that in both the above described embodiments of my invention, the counter mechanism is normally locked during weaving and that at the end of the day or the week, the supervisor is supposed to record the readings of one or both of the counters and to unlock and to reset the same. He can not, however, lock the counter mechanism and withdraw his key once he has initiated resetting of either counter until that counter has been completely reset to zero. 'lihus, it will be evident that, while the weaver is pre vented from fraudulent manipulation oi. the re= setting mechanism, carelessness on the part oi the supervisor is also prevented by requiring a complete resetting of either counter and locldng of both counters before he can withdraw his key.

Further, with the above described mechanism an operator obtaining a key can not advance a legitimate count by manipulating the resetting mechanism due to the presence of the ratchet and pawl construction which, upon even a slight movement of the resetting mechanism in a resetting direction, results in one of the spring pressed pawls dropping behind a tooth, thus, requiring a complete resetting movement to zero. Thus an. operator attempting to cheat in this manner in order to avoid detection with the key in his counter will be obliged to wipe out even the count which he has legitimately woven and, after being thus penalized, will ordinarily not again attempt to cheat in this manner.

The presence oi the ratchet and pawls also prevents numerous other forms of cheating. For example, it prevents .an operator who has obtained a key from fraudulently advancing the count at the beginning of the shift when the counter wheels are at zero position which, without the ratchet and pawls construction, he could do as follows: First, he would turn the counter resetting mechanism to read 999 and weave 2,000 picks with the key in the lock. The counter would then read 001. He would then turn the resetting member backward until he had picked up the lowest order number wheel, but without turning back enough to pick up the other number wheels. He would then turn ahead the resetting mechanism to the normal reset position thereof follow ing which movement the number wheels would read 010. Then he would lock the counter mechanism and remove the key and really start his day's work with a credit for 10,000 picks. In the constructions above described, however, the operator would be unable to perform this type of manipulation since he can not turn back the wing nut i0. shown in Figures 1-1411, he would be obliged to start by turning up 7'77 which would, of course, subject him to a wholly unreasonable risk as a supervisor might come at any time while he was weaving the required 223,000 picks and to avoid detection, he would have to wipe out his whole count and start over. Obviously, if desired, instead of using four teeth, the number of teeth may be increased. In the modified construction including the gear 50 and pawl 00, reverse rotation of the resetting mechanism is prevented throughout the entire range of resetting movemerit.

Attention is also directed to the fact that in both constructions herein disclosed the mechanism is proof against fraudulent advance of the count by tapping on the resetting mechanism, i. e., by striking the resetting member l0 a sharp blow by any suitable instrument, both when the counter is locked and when it is unlocked. Such advance when the counter mechanism is locked is prevented in my improved construction by the camming action of the locking plate acting on the cooperating rotatable locking members to reversely rotate the latter and cause the resetting grooves 23 to be withdrawn from the reset pawls 2t; before the counter mechanism can be locked and the key withdrawn. Thus, it will be evident that it is impossible to transmit a blow on a resetting member 00 through the resetting shafts 6 and U to the ends of the reset pawls it in such manner that the counter wheels will be advanced beyond zero.

Advance by tapping on the resetting member id immediately following resetting and prior tolocking is prevented by the no-reverse mechanism including the spring pressed pawls acting on the ratchet wheels ib or the gear 50. These cooperating members provide sufiicient frictional restraint on the resetting mechanism to make it impossible for an operator to advance the counter wheels by a blow by holding the unlocked resetting member flil and striking a blow since, due to this frictional restraint, such a severe blow must be struck that the resetting shaft will be advanced sufficiently to allow one of the pawls to drop behind the next adjacent tooth, thus requiring a complete resetting movement of the resetting mechanism in order to permit locking and withdrawal of the key.

It will further be evident that as a result of the present improvements I have provided a sim- Instead with the constructionv plified locked counter mechanism of the pick counter type including a plurality of counters having a common lock cooperating therewith in an improved manner and without the necessity for the reciprocable locking member. Further by reason of the pawls and ratchets and the blow-proof structure, above described, a wholly new cooperation is provided between the resetting mechanism and the locking mechanism which produces an improved locked pick counter and one which an operator can not fraudulently advance even if he has a key. These and other objects and advantages of my improved construction will, however, be clearly apparent to those skilled in the art.

While I have in this application specifically described two embodiments which my invention may assume in practice, it will be understood that the same are shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
